If you are one of the lucky developers who has received a BlackBerry 10 Dev Alpha recently, you've probably done like most of us by loading apps, games, videos & music to test the capabilities & features of this development device.

When I originally sideloaded the Messages app (extracted from PlayBook OS 2.0.1), I noticed that the scaling/proportions were not compatible with the Dev Alpha's screen resolution.

With the recent release of PlayBook OS 2.1 Beta, it seems that the Messages app found within the OS loads proportionally on the Dev Alpha.
